of

be

is

and

market

> The PiezoTone hue gray sets are Warm Neutral, Selenium Tone, Cool Neutral,
> and Carbon Sepia. They comprise three gray dilutions available in 3 or 5
ink

The
> PiezoTone gray sets are made from 100% pigments without the use of dye or
> metal complex. They are all carbon based with additional pigments added
for
> color. The Carbon Sepia is pure carbon without add'l pigments. If you
liked

> you will like this ink very much as it has the warmth but without the
> density loss. Also the ink has been shaped to maintain the same
directional
> facets when dried down. There is nil metamerism and the ink can pick up
> subtle hue differences depending upon paper. Very platinum like. Cool
> Neutral is just off neutral to the cool side and does not have the blue
look
> of the other cool neutrals.

> The choice of blacks is going to expand to include inks which are suitable

use

of

> PIezoTone black has a very high Optical Density which was the highest

> software it was not expected to produce any fade results which were

the

about

the

the

of

11%
